PRIORITY CLAIM

This application claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Application Ser. No. 63/040,689, entitled “Improved Golf Mat,” filed on Jun. 18, 2020, the entire disclosure of which is relied upon and incorporated by reference herein for all purposes.

TECHNICAL FIELD

Embodiments of the present invention generally relate to golf mat systems and assemblies, and to associated methods for using a golf mat.

BACKGROUND

It is known to provide a mat to practice and refine skills used in playing various sports. In the case of golf, such practice mats typically comprise a somewhat flexible material (e.g., rubber) topped with an artificial grass surface configured to replicate the conditions of one or more hitting or putting surfaces encountered on a real golf course, such as tee boxes, fairways, rough, and putting greens. These mats typically are square or rectangular in shape and at least somewhat portable, and they may also be paired with nets or backstops. Thereby, users of such a mat may practice their swing or actually hit, chip, or putt both indoors and outdoors. Such mats also are commonly used in conjunction with golf simulators.

The foregoing discussion is intended only to illustrate various aspects of the related art in the field of the invention at the time, and should not be taken as a disavowal of claim scope.

In fact, it will be apparent to those skilled in the art that modifications and variations can be made in the present invention without departing from the scope or spirit thereof. For instance, features illustrated or described as part of one embodiment may be used on another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

Further, either of the terms “or” and “one of ______ and ______,” as used in this disclosure and the appended claims is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from the context, either of the phrases “X employs A or B” and “X employs one of A and B” is intended to mean any of the natural inclusive permutations. That is, either phrase is satisfied by any of the following instances: X employs A; X employs B; or X employs both A and B, regardless whether the phrases “at least one of A or B” or “at least one of A and B” are otherwise utilized in the specification or claims. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from the context to be directed to a singular form. Throughout the specification and claims, the following terms take at least the meanings explicitly associated herein, unless the context dictates otherwise. The meanings identified below do not necessarily limit the terms, but merely provide illustrative examples for the terms. The meaning of “a,” “an,” and “the” may include plural references, and the meaning of “in” may include “in” and “on.” The phrase “in one embodiment,” as used herein does not necessarily refer to the same embodiment, although it may.

As noted above, certain embodiments of the present invention provide golf mat systems and methods. Certain embodiments are described below in the context of a mat used for practice of and instruction regarding a golf swing, but those of skill in the art will appreciate that the present invention is not so limited. Among other things, for example, mats in accordance with embodiments of the present invention may be used for sports other than golf or for exercise or workouts.

Referring first to FIGS. 1-6, in one embodiment, a golf mat 100 is provided. Golf mat 100 in this embodiment comprises a first portion 102, a second portion 104, a third portion 106, and a fourth portion 108. First portion 102 in this embodiment is foldably coupled with second portion 104 at a hinge 110; second portion 104 is foldably coupled with third portion 106 at a hinge 112; and third portion 106 is foldably coupled with fourth portion 108 at a hinge 114. Together first portion 102 and second portion 104 may comprise a hitting side 116 of golf mat 100, and third portion 106 and fourth portion 108 may together comprise a putting side 118 of golf mat 100. Although four portions 102, 104, 106, and 108 are provided in this embodiment, those of skill in the art will appreciate that in other embodiments any number of portions may be provided.

Golf mat 100 may be formed of a variety of suitable materials familiar to those of skill in the art. In general, golf mat 100 may be formed from a lightweight, flexible material of suitable strength and resilience for repeated use as a golf practice mat. In some embodiments, golf mat 100 may be formed from a natural or synthetic elastomeric material, such as from any suitable rubber material. Golf mat 100 may also be a composite of several materials, such as a substrate formed from a natural or synthetic elastomeric material to which one or more layers of artificial turf is applied.

Additionally, golf mat 100 may have a top surface 101 and a bottom surface 103, each of which may extend across first portion 102, second portion 104, third portion 106, and fourth portion 108. In various embodiments, top surface 101 and/or bottom surface 103, or any portion(s) thereof, may comprise the artificial turf or grass material, embodiments of which are described in more detail below. In various embodiments, different portions 102, 104, 106, and/or 108 may have the same artificial surface as, or a different artificial surface from, one another. Additionally, and also as described herein, mat 100 may be used in conjunction with one or more additional artificial turf or grass pieces which may represent different types of grass or turf from the artificial turf of mat 100.

Hinges 110, 112, and 114 are adapted to allow golf mat 100 to be folded into a variety of shapes and/or positions, such as to mimic various golf shot lies and/or so that the golf mat 100 may be carried, as described herein. Accordingly, in various embodiments, and depending on the material(s) selected for golf mat 100, hinges 110, 112, 114 may comprise any suitable hinge familiar to those of ordinary skill in the art. In one preferred embodiment, hinges 110, 112, and 114 may be constructed using a suitable tape 119 (see FIG. 4).

Hinges 110, 112, and 114 may be adapted to allow folding of portions 102, 104, 106, and 108 relative to one another in any direction. For example, in the embodiment shown, first portion 102 is foldable relative to second portion 104 about hinge 110 only in the direction that allows the top surface 101 of first portion 102 to come into contact with the top surface of second portion 102, and third portion 106 is foldable with respect to fourth portion 108 about hinge 114 only in the direction that allows the top surface 101 of third portion 106 to come into contact with the top surface of fourth portion 108. Thus, for example, where tape is used to construct hinges 110, 114, the tape may be applied on the top surface 101 side of golf mat 100, though such tape may be concealed beneath the artificial turf material. This allows the bottom surface 103 edges of hinges 110, 114 to move away from one another during folding. In contrast, second portion 102 is foldable relative to third portion 106 about hinge 112 only in the direction that allows bottom surface 103 of second portion 104 to come into contact with the bottom surface 103 portion of third portion 106. Thus, for example, where tape is used to construct hinge 112, such tape 119 may be applied to the bottom surface 103 side of golf mat 110, between second portion 104 and third portion 106 (see FIG. 4). Among other things, this construction allows a user to fold golf mat 110 into an easily-carriable configuration as shown in FIGS. 7-8. Of course, in various other embodiments, this configuration may be reversed, such that hinge 112 allows the top surfaces 101 of second portion 104 and third portion 106 to come into contact with one another, while hinges 110 and 114 fold the opposite direction. Additionally, hinges 110, 112, and/or 114 may be bidirectional hinges.

In various embodiments, golf mat 100 (including any of first, second, third, or fourth portions 102, 104, 106, and/or 108) may have any shape. In some embodiments, for example, golf mat 100 may be rectangular in shape, as may portions 102, 104, 106, and/or 108. In other embodiments, mat 100 may be triangular or trapezoidal in shape, as may portions 102, 104, 106, and/or 108.

In one preferred embodiment, when viewed in plan (see FIG. 3), hitting side 116 and putting side 118 may each resemble a disc or circle having a circular segment “cut off” therefrom. The cut off circular segment may define a secant or chord that is represented by edges 120, 122 on each of hitting side 116 and putting side 118. Hitting side 116 and putting side 118 may then be attached together at edges 120, 122. In other words, hinge 112 may be defined between edges 120, 122. In various embodiments, forming mat 100 in this shape may decrease the weight of the folded mat, which makes it easier to carry and store. Additionally, in some embodiments, this shape may confer benefits in terms of less storage space needed to store the mat and overall aesthetic appeal. Further, in some embodiments, this shape may encourage a golfer to “swing (the body) inside the barrel.”

Similarly, in the illustrated embodiment, first portion 102 may resemble a circle having a circular segment cut off therefrom. The missing circular segment may define a chord represented by edge 124. Second portion 104 may resemble a circle having two circular segments cut off therefrom. The missing circular segments may define a chord represented by edge 126 and edge 120, described above. Accordingly, hinge 110 may be defined between edges 124, 126. Third portion 106 and fourth portion 108 may be formed in similar fashion, such that in addition to edge 122, third portion 106 defines an edge 128, and fourth portion 108 defines an edge 130. Hinge 114 may be defined between edges 128, 130. In some embodiments, hinges 110 and 114 may be defined along diameters of the circles that hitting side 116 and putting side 118 are defined from (i.e., diameters of what would be circles had there not been circular segments cut off at edges 120, 122), such that first portion 102 and fourth portion 108 each are semicircular in shape when viewed in plan.

A plurality of apertures 132 may be defined in hitting end 116. As shown, seven (7) such apertures 132 are defined in hitting end 116 in this embodiment, but any suitable number of apertures, in any arrangement, may be provided in other embodiments. Apertures 132 may extend partially or entirely (see FIG. 4) through hitting end 116 in various embodiments. As described in more detail herein, apertures 132 may be sized to receive a golf tee so that a user of mat 100 may “tee off” (using a driver or any other club) from any position defined by an aperture 132. The locations of apertures 132 may vary in various embodiments, as needed or desired. Apertures 132 may be arranged in a “v”-shaped pattern, e.g., as shown, such that the apertures 134 closest to the peripheral edges of first portion 102 are farthest away from hinge 110, and the aperture 134 in the center is closest to hinge 110. In various embodiments, this pattern may show any desired swing path for left- or right-handed individuals. Again, though, other configurations are contemplated.

Additionally, apertures 134 may be defined in either or both of hitting side 116 and/or putting side 118. Apertures 134 may be larger in diameter than apertures 132 in some embodiments and may also extend partially or entirely (see FIG. 4) through golf mat 100 in various embodiments. For example, apertures 134 may be sized such that a golf ball may be received partially or entirely therein in some embodiments. As described in more detail herein, apertures 134 may be used for practicing putting exercises or playing putting games on mat 100. Three (3) apertures 134 are shown in the figures, but those of skill in the art will appreciate that any number of apertures 134 may be provided in other embodiments, and in additional or different configurations, as needed or desired.

As best seen in FIGS. 1 and 5-6, golf mat 100 (including each of first, second, third, and fourth portions 102, 104, 106, and 108) may define a peripheral surface 136. Peripheral surface 136 may have a height H corresponding to the thickness of golf mat 100. As will be appreciated, in some embodiments each of first, second, third, and fourth portions 102, 104, 106, and 108 may have a different thickness or may have the same thickness. As shown, first, second, third, and fourth portions 102, 104, 106, and 108 each have the same thickness, which may be about 1″ in some embodiments.

In some embodiments, apertures 138 may be defined in one or more portions of peripheral surface 136. For instance, as shown in FIG. 6, four (4) apertures 138 may be defined in putting end 118, for example centered with respect to apertures 134, though in other embodiments any number of apertures 138 may be provided. As described in more detail herein, apertures 138 may be sized to receive a suitable attachment mechanism, such as a golf tee or the like. Thereby, the attachment mechanism may be used to secure a backstop in a vertical fashion relative to golf mat 100 such that, for example, a rounded vertically-extending surface projects above top surface 101 and partially surrounds apertures 134. This may facilitate putting exercises, for example, by blocking a hit golf ball from rolling off of golf mat 100 and/or (because of the curved surface) by returning a golf ball to a user. As described in more detail below, in some embodiments, such a backstop may be formed from one of the cut off circular segments from hitting portion 116 and/or putting portion 118 of golf mat 100.

In various embodiments, apertures 132 may be filled with a removable plug 140 (see FIG. 7), and apertures 134 may be filled with a removable plug 142 (see FIG. 8). Plugs 140, 142 may be formed from the same material(s) as golf mat 100 in various embodiments, such that apertures 132 and 134 may be concealed when not in use. In some embodiments, apertures 138 may also be filled with a removeable plug (not shown).

Finally, in various embodiments, golf mat 100 may be provided with indicia 144. Indicia 144 may be defined on top surface 101, bottom surface 103, and/or peripheral surface 136, as needed or desired. Indicia 144 may be painted, drawn, or otherwise applied in a sufficiently permanent or non-permanent fashion. As those of skill in the art will appreciate, and as described in more detail herein, indicia 144 may be used, for example, for instructional purposes, such as but not limited to measure shots, align or position a user's feet or his club head, and illustrate direction. One example of indicia 144 is shown in FIGS. 1-3, but any suitable indicia may be provided in other embodiments.

Embodiments of the present invention also include a process for manufacturing a golf mat. In accordance with one such embodiment, first, two circular pieces are cut from a sheet of high density, closed cell foam rubber. In some embodiments, laser cutting may be used. Although golf mats in accordance with embodiments of the present invention may have any suitable dimensions, in one embodiment the circles may have a diameter of about 38″. These circles next each may be cut across their diameters, and then each cut again to remove a circular segment therefrom.

The removed circular segments (which may resemble a semi-circle or half-moon), may then be adapted for use as a putting backstop and/or for creating/manipulating undulations under the mat. The remaining four pieces of the two circles may form portions analogous to first, second, third, and fourth portions 102, 104, 106, and 108, described above. Weights may be used to flatten the edges of these four pieces, particular where the circles were cut from foam rubber that is provided on a roll.

Then, any suitable number and/or configuration of apertures may be cut out of each of the circle portions. The cut-out portions may be retained for use as removable plugs.

Next, the two pieces of each of the two original circles may be foldably coupled together. For example, hinges may be construed between each two pieces of each original circle. In one embodiment, tape may be used to create the hinges. In various embodiments, suitable industrial tape may be used. At each hinge, tape is first applied to the top side or bottom side of the two pieces that will be foldable relative to one another, depending on the direction of desired folding. These portions may then be folded relative to one another, and when in this folded position, additional tape may be applied at the hinge, as needed or desired.

Next, artificial grass turf of any suitable style or thickness is cut from a suitable sheet or roll. In various embodiments, the artificial grass turf may be about 0.25″ in thickness and may be selected according to golfer preferences. For instance, a “fine” or “low” cut turf may be desirable for good putting and feel. The artificial grass or turf may be cut out to fit the shape of the original circle piece, but with room to trim. Suitable adhesive (e.g., glue) is applied to the top side of the rubber pieces and to the bottom side of the turf, and the turf is laid carefully on top of the rubber portions. In some embodiments, contact cement may be used to secure the artificial turf to the rubber pieces. (Prior to doing so, in various embodiments, the “plugs” cut out for the apertures may be returned to their corresponding apertures to allow turf to be applied thereto.) Other suitable mechanisms for fastening may be used in other embodiments. Once the turf is disposed on the rubber portions, the tape used to create the hinges may be at least partially concealed by the turf.

The turf is then stretched and tightened around the edges (e.g., analogous to peripheral surface 136, described above). (In various embodiments, for putts to roll across the two circle pieces without interference, the turf should go all the way around even where the two circles connect.) The removed circular segments (or “satellite” pieces) may be added to each circle to re-complete the circle and to hold the turf in place against the chord, or edge, where the circular segment was removed. The completed circle may be wrapped with a strap and tightened for a suitable duration to allow the adhesive to cure. In some embodiments, the curing time may be two or more days.

Excess turf material may be trimmed from around the edges of the rubber material. Additionally, the plugs may be trimmed at the turf so that the plugs may be removable. Then, all of the cut turf edges may be singed or burned to keep them from unraveling, if needed.

Once this has been completed for both original circles, and once the adhesive has cured, each of the original circles may be foldably coupled together at the edges that correspond to the chord defined by the cut out circle segments. Each of the original circles may be turned upside down and disposed such that their straight edges are adjacent and aligned. Industrial tape (e.g., tape 119 in FIG. 4) may be applied across the interface between these two original circles to secure these portions together, creating a hinge analogous to hinge 112 described above. Then, the entire mat may be turned back over and folded at this hinge, and additional tape may be applied to this hinge, as needed.

As needed or desired, at any or all hinges, additional tape 145 (which may be a contrasting color) may be used to “trim” the tape used to form the hinges (see FIGS. 4, 13-14). Doing so may provide a clean and pleasing look to the hinges of the mat.

If indicia is to be applied to the mat, the indicia desired may first be defined in a suitable stencil. Then, the stencil may be placed on top of the mat and paint (or another marking material) may be applied over the stencil. In one embodiment, the design may be painted with “satin jade” spray paint made by Krylon.

In some embodiments, the completed mat may weigh about 12 pounds, and may be about 65″ long (unfolded), and 38″ wide. Some embodiments may fit into a 20″×40″×4″ box when folded.

Next, FIGS. 7 and 8 are respective left side and right side perspective views of a golf mat assembly 200 in accordance with another embodiment of the present invention. Golf mat assembly 200 comprises golf mat 100 in this embodiment. In FIGS. 7 and 8, golf mat 100 has been folded as described above, such that the top surface 101 of first portion 102 is folded about hinge 110 toward top surface 101 of second portion 104, top surface 101 of fourth portion 108 is folded about hinge 114 toward top surface 101 of third portion 106, and bottom surface 103 of second portion 104 is folded about hinge 112 toward bottom surface 103 of third portion 106. As a result, golf mat 100 is moved from an open position, in which portions 102, 104, 106, and 108 lie flat, to a folded position in which portions 102, 104, 106, and 108 each are disposed in a vertical orientation. The folded position of golf mat 100 may resemble a taco in this embodiment. A strap 202 may then be passed through apertures 134, on each of first portion 102 and fourth portion in order to secure the golf mat 100 in the folded position and to permit carrying or transport thereof.

In various embodiments, and as described in more detail with reference to FIGS. 7-16, golf mat assembly 200 may comprise a number of other components. Such components include, but are not limited to, a measuring tape 204 (see FIGS. 11-12), clips 206 (see FIGS. 11-12 and 14-16), tees 208 (see FIGS. 7-8 and 10-12), balls 210 (see FIGS. 8-16), and clubs 212 (see FIGS. 7 and 9-16). Clips 206 may be any suitable clip mechanism familiar to those of skill in the art, and in the illustrated embodiment clips 206 are analogous to legal clips. In some embodiments, tees 208 may be various sizes. As shown in FIGS. 7 and 8, tees 208 may be stored or disposed in apertures 138. Further, a tee 208 sized for removable engagement with apertures 132 may be coupled with measuring tape 204, as best seen in FIG. 12.

Further, golf mat assembly 200 may include circle segments 214, 216 and artificial turf mats 218, 220. Segments 214, 216 and mats 218, 220 are not coupled with mat 100 and may instead be used to configure mat 100 for various practice shots and instructional set ups, as described by way of the examples herein. Circle segments 214, 216 (see FIGS. 7-10) may be made from the portions of the original circles used to construct mat 100, as described above. In some embodiments, circle segments 214, 216 are not provided with artificial turf. Circle segments 214, 216 may have an aperture 222 defined therethrough to receive strap 202, as shown in FIGS. 7-8. Thus, circle segments 214, 216 may be secured to and carried with the folded golf mat 100 by being secured between first portion 102 and fourth portion 104. Additionally, the portions of circle segments 214, 216 that are removed to define apertures 222 may be retained as a removable “plug.” These plugs may be reinserted into apertures 222 for use in putting practice (e.g., a user may attempt to knock the plug out of the aperture 222 with a firm, uphill putt).

Referring now also to FIGS. 9-10, either or both circle segment 214, 216 may also have apertures 224 defined therethrough. Apertures 224 may correspond to and be similar in size to apertures 138 defined in peripheral surface 136. Thereby, circle segments 214, 216 may be secured to peripheral surface 136 via a suitable attachment mechanism, such as a golf tee. As shown, a circle segment 214 or 216 may then be used as a backstop for putting and, due to the curved surface thereof once attached to peripheral surface 136, circle segments 214, 216 may also act to return or redirect back toward the user a ball that has been hit at, but which missed, an aperture 134. (In FIG. 9, balls 210 are shown sitting in apertures 134.) The other circle segment 214 or 216 may be disposed under a portion of golf mat 100 to mimic undulations in the putting surface.

Artificial turf mats 218, 220 (see FIGS. 10-12, 14-16) may be any shape, but as shown in one embodiment, mats 218, 220 may have a semicircular shape similar to that of first portion 102 and fourth portion 108. Artificial turf mats 218, 220 may comprise or be adapted to resemble any turf variety, but in one embodiment mats 218, 220 have a different turf variety than that of portions 102, 104, 106, and/or 108 of mat 100. In one embodiment, at least one of the artificial turf mats 218 or 220 may have apertures 226 defined therethrough that correspond to (e.g., in size and/or number) and which may be aligned with apertures 132 in first portion 102 when the artificial turf mat is disposed on the top surface 101 thereof such that a tee may be received through both an aperture 226 and an aperture 132 (see FIG. 11). In some embodiments, at least one of the circle segments 214, 216 may have apertures 227 (see FIGS. 7-8, 10) analogous to apertures 226 and which correspond to (e.g., in size and/or number) and which may be aligned with apertures 132 in first portion 102 when the circle segment is disposed above or below top surface 101 thereof. Additionally, either or both artificial turf mat 218, 220 may have an aperture 228 defined therethrough analogous to apertures 134 defined in first and fourth portions 102, 108 of mat 100 and to apertures 222 defined in circle segments 214, 216. Thereby, artificial turf mats 218, 220 also may be carried with golf mat 100 and circle segments 214, 216 via strap 202 passing through apertures 134, 222, and 228.

In various embodiments, golf mat assembly 200 and components thereof may be used to configure mat 100 to practice or receive instruction on a variety of golf shots. A number of examples are shown in FIGS. 9-16. For instance, as noted above, FIGS. 9-10 show golf mat 100 configured for putting practice. FIG. 11 is a top side plan view of golf mat 100 configured to practice driving. Here, both artificial turf mats 218, 220 are disposed on top surface 101 of golf mat 100. Turf mats 218, 220 may be secured to golf mat 100 via any suitable attachment mechanism, in this case clips 206. Turf mats 218, 220, which in this embodiment may mimic a tee box of a golf course, may be aligned with the peripheral edges of golf mat 100 or a portion of indicia 144, as shown. Measuring tape 204 is used to measure the distance between the tee 208 and the user's feet. In similar fashion, FIG. 12 is a top side plan view of golf mat 100 configured to practice a mid-iron.

Next, FIG. 13 is a top side plan view of golf mat 100 configured to practice a swing wherein the golf ball 210 is positioned below the user's feet. Here, fourth portion 108 has been folded over at hinge 114, while first, second, and third portions 102, 104, and 106 remain flat on the ground. The user may stand on the bottom surface 103 of fourth portion 108, and the ball 210 may be placed on top surface 101 of first portion 102. Thus, the ball 210 is below the level of the user's feet. FIG. 14 shows a similar arrangement wherein golf mat 100 is configured to practice a swing wherein the golf ball 210 is positioned above the user's feet. In FIG. 14, first portion 102 has been folded over at hinge 114, while second, third, and fourth portions 104, 106, and 108 remain flat on the ground. Additionally, artificial turf mats 218, 220 have been placed on first portion 102 and fourth portion 108 to provide a different hitting surface. The user may stand on the top surface 101 of fourth portion 108 (on artificial turf mat 218) and the ball may be placed on the bottom surface 103 of first portion 102 (on artificial turf mat 220). Thus, the ball 210 is above the level of the user's feet.

Additionally, FIG. 15 is a perspective view of golf mat 100 configured to practice a swing wherein the golf ball 210 is positioned in an uphill lie, and FIG. 16 is a perspective view of golf mat 100 configured to practice a swing wherein the golf ball 210 is positioned in a downhill lie. To create these configurations, third portion 106 is folded at hinge 114 such that top surface 101 of third portion 106 is moved toward the top surface of fourth portion 108. As this occurs, hinge 112 is opened as hitting portion 116 (including first portion 102 and second portion 104) remains lying flat but is moved toward fourth portion 108. As a result, third portion 106 is disposed underneath hitting portion 116 and over fourth portion 108. (A similar arrangement may be created in the opposite direction, using second portion 104 instead of third portion 106.) This creates an inclined surface on top surface 101 of first portion 102. Additionally, in some embodiments, a user may position either or both of the circle segments 214 and/or 216 underneath a portion of hitting portion 116 (such as beneath first or second portions 102 or 104 in FIGS. 15 and 16) in order to support the inclined surface and/or to increase the degree of incline. Where either or both circle segments 214, 216 are disposed beneath first portion 102, for example, the straight side of the circle segments 214, 216 may be disposed about 3″ from the folded hinge 114. A user can stand on either side of this inclined surface, placing ball 210 on the opposite side, to create an uphill lie (as shown in FIG. 15) or a downhill lie (as shown in FIG. 16). Also as shown in FIGS. 15-16, artificial turf mats 218, 220 may be attached to golf mat 100 in this configuration.

Those of ordinary skill in the art will appreciate that numerous other shots may be practiced in other configurations. Those of skill in the art will also appreciate a number of advantages provided by embodiments of the present invention. For example, golf mats in accordance with various embodiments can withstand a lot of shock impact without harming a user's hands, body, club, or the mat. Embodiments of the mat or mat assembly may be water resistant and can be left outside. Further, embodiments may be used in the home, office, driving range, backyard, cruise ship, schools, or setup for video practice and fittings, among other locations. Embodiments may be used in virtual golf with real challenges, like an uphill 146 yds, in the rough or fairway. Some embodiments perform best on a solid surface, such as hardwoods and/or concrete, rather than on top of softer surfaces like rugs or other golf mats.

Certain indicia provided on the mat in various embodiments may be designed to show the golfer perfect square to the ball and target line. For example, indicia may comprise all right angles in front and back of the middle stance position, which aligns with the corresponding lines from ball to feet, set to the direction of the 2 large direction arrows. The golfer can always see where the ball and stance direction are related anywhere on the mat. Indicia also may be designed to help show a correct “in to out” swing path, e.g., down the target line when using the standard tee plugs. But, an “out to in” swing path can be provided or adjusted as well.

Embodiments of the mat allow the golfer to move the ball into various ball positions anywhere on the mat and know instantly if he or she is square to the ball and target line. The golf professional and professional club fitter can instantly “set up” the golfer for all of the basic golf swing theories, correct stance and drills, measurements. Embodiments of the mat also may be used as a “body alignment” stretching out mat for before and after a round of golf, or anytime, anywhere. Embodiments of the mat are easy on the back, elbows and knees.

In some embodiments, the mat may be used to practice fifty-four (54) or more shots other than a level tee box. In various embodiments, when folded, the mat can change size and shape for various lies for most any golf shot. When putting, embodiments of the mat may be used to practice 3 and 4 foot putts, or to play a game (e.g., three in a row). Embodiments of the mat may be set up straight or for breaking putts to 3 holes that are smaller than the ball, which will sit on the hole. As noted above, pitch angle can be added to the mat with the backstop, grass pieces, or plugs, and missed putts roll back in some embodiments. In various embodiments, the shock absorbing backstop allows the golfer to both practice and strike a firm uphill putting stroke, while indoors. To do this, the golfer aims to punch out a plug in the backstop.
